That removes all the fault tolerance. What do you do if you never get the acknowledgement from all replicas?

That question doesn’t make much sense. If you have quorum then eventually repairs will kick in and will get replicated everywhere.

So it can tolerate up to N/2 failures just like other consensus system. Because this is basically Raft.
